The minerals of the protolith may be pulverized and crushed by the high rate of shear strain that occurs in these zones. Rocks metamorphosed in these zones usually exhibit a combination of fractured, partly disintegrated, partly recrystallized versions of the original minerals, along with new mineral growth that occured during the metamorphism.
